So i had a major blow out a few days ago on one of my Yokohama avids. It did have a nail in it, but the entire inner side wall was blown out and torn to shreds. The tire place told me that the nail caused the puncture, obviously, and driving on it at a high speed caused the inside wall damage, but I fail to see the correlation between a nail puncture and a whole blow out. Can somebody please explain to me how it could cause that reaction? I feel that I've been duped.
